摘要： PROBLEM TO BE SOLVED: To provide a method for preventing the degradation in fatigue strength, due to surface roughening or hydrogen intrusion, of a titanium alloy part having been subjected to a plasma carburization treatment; and the titanium alloy part using the method. SOLUTION: After the solution treatment and aging treatment of a bolt material of a titanium alloy, the material is subjected to a plasma carburization treatment in an atmospheric gas with a temperature of 350 deg.C-700 deg.C and a pressure of 10-2,000 Pa, then heated at 150 deg.C-350 deg.C in an argon atmosphere, and subjected to thread form rolling. By the tread form rolling after the plasma carburization treatment, such form rolling effects that the work hardening layer at a thread valley bottom wherein fatigue fracture easily occurs is not softened, that the compression stress is not relaxed, and that the roughened surface due to the plasma charburization treatment is smoothened are secured; and the fatigue strength of the titanium alloy thread part is improved.

摘要： PROBLEM TO BE SOLVED: To easily mount a backing sheet layer on a steep slope or on an easy slope by forming the backing sheet layer from nonwoven fabric cloth, woven cloth, etc., between the whole area of which a conductive sheet is disposed, and constituting a seepage control layer with a waterproof layer consisting of a waterproof material, such as a quick setting liquid resin material, sprayed and fixed on the whole surface of the backing sheet. SOLUTION: A recessed part 3 is formed on the ground 2 to be made into a final waste disposal site, and seepage control layer 1 is laid on the bottom of and on the slope surface of this recessed part 3. In this seepage control layer 1, a backing sheet layer 7 is formed with a backing sheet consisting of nonwoven fabric cloth the whole area of which a conductive sheet 4, such as an aluminum sheet, a copper sheet, and a geosynthetic clay liner, is laid. At a field, a waterproof material 8 such as a quick setting liquid resin material is sprayed and fixed on the whole surface of the backing sheet of this backing sheet layer 7 so as to be a prescribed thickness, thereby a water resistant layer 9 is formed. In such a way, the backing sheet layer 7 can be easily installed on a steep slope and on an easy slope.

摘要： PROBLEM TO BE SOLVED: To provide an inexpensive air supply and exhaust device for a kitchen with a simple structure which does not exert an influence on the air-conditioning of the kitchen, not generate an uncomfortable air flow for a cook in the kitchen, not put out the flame of a gas range and does not diffuse fine grains of oil, etc., to surroundings. SOLUTION: A floor plate 21 is removed and an air inlet port 4 is formed in an air flow passage 2 with no bottom plate formed in the interior of a housing part in a range base 1. An air flow space 26 above the housing part in the range base communicates with the air flow passage 2. Many air outlet holes 8 communicating with the air flow space are provided on three sides on the peripheries of both the side surfaces and the wall side surface of a mount face of a gas range 7 7 on the range base and air outlet ports 9 are provided in the front face plate plate of the range base. Air sucked from an underfloor is supplied from the air outlet ports 8 and the air outlet ports 9 only by the operation of an exhaust fan 10 in an exhaust duct 16 communicating with an exterior and a rectifying plate 15 provided on a wall surface. Thus, an air curtain formed on the front surface surface, both the side surfaces and the wall surface above the range base surround smoke or the like generated from the gas range 7 in a kitchen to guide it an exhaust port 19 and exhaust it to the exterior.

摘要： PROBLEM TO BE SOLVED: To provide the subject simplified device designed to efficiently and accurately transfer a genetic material into a plant tissue through ensuring the genetic material to be directly exposed to gas pressure and improving the structure of a filter to mount the genetic material on. SOLUTION: A hard disc-shaped filter with many perforations is housed inside a cartridge 11 connected via relevant means 20, 22, 24 to a gas force feed channel. DNA-coated metallic particles 70 are put on the upper surface of the filter 50. A helium gas subjected to force feed by releasing an electromagnetic valve directly collides against the DNA-covering metallic particles 70, emits them and drives them into a target 120. The distance between the filter 50 and the target 120 can be controlled by vertically moving a shelf board 110.
